Keep option selected - php

Question

I have a selectbox with some values, i inserted those values inside an array.
Now i want to select some specific option, and keep the option selected even when the page reloads.
$logos =array('logo1', 'logo2', 'logo3');
echo '
<td class="jofftd">
<label>Platform</label>
<select name="searchpt">
<option value="0">All</option>
';
foreach ($logos as $value)
{
echo '
<option value="'.$value.'">' .$value . '</option>
';
}
echo '
</select>
</td>';
I would need to do something like this:
foreach ($logos as $value)
{
echo '
<option';
if ($value == $value) echo 'selected="selected"';
echo 'value="'.$value.'">' .$value . '</option>
';
}
But it doesn't work.
Thanks.

Answer 1

Assuming you are using a POST method form, the code would look something like this (note: not tested)
foreach ($logos as $value)
{
$selected = ($value == $_POST['searchpt']) ? ' selected' : '';
echo '<option'. $selected . ' value="'.$value.'">' .$value . '</option>';
}

Answer 2

If nothing else, you're missing at least one space character:
<option';
if ($value == $value) echo 'selected="selected"';
This will produce
<optionselected="selected"
which is not exactly valid HTML.
Plus, $value==$value will always be true, so even if you had proper spacing in the tags, you'd be marking ALL of the options as selected. You need to compare the $value from the loop against the value from the original form, e.g.
if ($value == $_POST['field_from_previous_form'}) { ... }

Answer 3

$value == $value will be always true and it will always add selected = "selected"
use string concatenation to form select form field.
<?php
$logos =array('logo1', 'logo2', 'logo3');
$value = 'logo1';
$str = '<select name="searchpt"><option value="0">All</option>';
foreach ($logos as $value)
{
$str.='<option ';
if ($value == 'logo1')
$str.=' selected="selected "';
$str.=' value="'.$value.' ">' .$value . ' </option> ';
}
$str.='</select>';
echo $str;
?>
Hope this code snippet will solve your problem
